Further confirmation of the hypothesis that there was a regular export of metals from Attika to Egypt around 1400 bc comes from the analysis of the copper in a bronze dagger with an inscription of Amenōphis III found at Beth Shan in Palestine, which indicates that it probably came from Laurion.

Megara was situated on the Isthmus of Corinth, bounded by the Corinthian Gulf on the north, Mts. Kithairon, Pateras and Kerata on the east, separating Megarian territory from Attika and Boiotia, the Saronic Gulf on the south, and Mt. Gerania on the west, dividing Megaris and Corinthia.

Oinokhoai also served domestic needs, but almost exclusively in Attika (Athenian Agora 253-261). A single example is known from overseas (Berezan 267). Only two early sixth-century oinokhoai were found in sanctuaries, in both cases outside Attika (Naukratis 262, Gravisca 265).
